BACKGROUND The operative treatment of adult degenerative scoliosis combined with osteoporosis increase following the epidemiological development. Studies have confirmed that screws in osteoporotic spines have significant lower-screw strength with more frequent screw movements within the vertebra than normal spines. Screws augmented with polymethylmethacrylate (PMMA) or with autogenous bone can ...

OBJECTIVES This study was undertaken to evaluate the effect of hyperbaric oxygen (HBO) on the repair of critical-sized defects in the presence and absence of a nonvascularized autogenous bone graft. STUDY DESIGN Ten New Zealand White rabbits were randomly divided into 2 groups of 5 animals each. Bilateral 15-mm calvarial defects were created in the parietal bones of each animal, resulting in ...

BACKGROUND Patients with ankylosing spondylitis (AS) achieve early bone union compared to those with other spinal diseases. This study compared the time to bone union after surgery between AS patients and degenerative spinal disease patients. METHODS Patients with degenerative spinal diseases (control group) and AS (experimental group) underwent pedicle subtraction osteotomy followed by poste...

IN nasal surgery, cartilage or bone transplants are required for support or correction of cosmetic deformities. When autogenous material is readily available, it should be used in preference to homogenous or heterogenous material. Sometimes this means, however, an iliac bone or rib cartilage graft. These procedures have a certain morbidity and the grafts are not always readily accepted by the p...

STUDY DESIGN Economic evaluation provides a framework to explicitly measure and compare the value of alternative medical interventions in terms of their clinical, health-related quality-of-life, and economic outcomes. Computerized economic models can help inform the design of future prospective studies by identifying the cost-drivers, the most uncertain parameter estimates, and the parameters w...

We performed curettage followed by autogenous bone grafting in several cases of steroid-related osteonecrosis of the femoral condyle, and reviewed the outcome of this procedure after a mean follow-up of 9.5 years. The number of patients was 4; the mean age at the time of the operation was 30.5 years. The mean Knee Society Objective Score was 52.5 before the operation and had increased to 87.5 a...

Anterior calcaneal osteotomy (ACO) with extension bone graft is commonly employed in the treatment of symptomatic supple, hypermobile flatfoot in adolescent as well as adult (>or= 18 years of age) patients. Although autogenous bone graft has been considered the gold standard, allogenic bone is widely used for this procedure because it is readily available, requires no additional procedure for p...

BACKGROUND Various instruments have been developed for collecting bone debris during intraoral autogenous bone graft procedures in implant surgery. The aim of this study was to quantitatively determine the degree of contamination in bone debris collected by different devices. METHODS Twelve patients underwent autogenous bone collection using a bone chisel, bone scraper, trephine drill, and bo...

The gold standard following segmental mandibulectomy is vascularized autologous bone graft in the form of the fibula flap. However, in bone reconstruction the use of autogenous bone does not always guarantee a successful outcome. The aim of the present investigation was to develop a novel biologically active bone (BAB) graft, and to use it for the reconstruction of large size defects of the man...

A 60-year-old man with missing maxillary molar teeth received dental implant therapy for reconstruction of occlusion. Sinus floor elevation with autogenous bone graft consisting of iliac bone block and particulate cancellous bone and marrow (PCBM) was performed in the bilateral maxillary sinuses for implant placement. On the right side, bone height in the molar region was less than 2mm. Therefo...
